// Users.js

const users = [
    {
        id: 52325,
        name: 'Bob Sponge',
        age: 23
    },
    {
        id: 19473,
        name: 'Squidward Tentacles',
        age: 35
    },
    {
        id: 58237,
        name: 'Mr. Krabs',
        age: 45
    }
];

module.exports = users;

// index.js

const express = require('express');
const users = require('./Users');
  
const app = express();
 
app.get('/users', (req, res) => res.json(users));
  
const PORT = process.env.PORT || 8080;
  
app.listen(PORT, () => console.log(`Server started on port ${PORT}`));
  
 
  
  
/*
